Homework Statement
a 500 kg satellite experiences a gravitational force of 3000 N, while moving in a circular orbit around the earth.
a) Find the radius of the circular orbit
b)Find the Speed of the Satellite
c) Find the period of the orbit
Homework Equations
g=GM1M2/r2
Fc=Mv2/r
V=2∏r/T
The Attempt at a Solution
a)g=GM1M2/r2
Fnet = GM1M2/r2
r=√(6.67x10-11)(5.98x1024)(500)/3000 N)
r=8.15x106
b)3000 N= (500)V2/(8.15x106)
V=6994 m/s (25, 178 km/hr)
c) V= 2∏r/T
T=2∏r/V
T=7321.7 S (2.03 h)
Does everything look okay, I am really usure of my understanding of gravitational forces.. Thanks!
Fnet=MV2/r
